O'Connor, who suffers with mental illness, has been open about her struggles with manic depression in the past.

Sinead O’Connor, the 48-year-old Irish singer who stole hearts around the world with her 90s hit NothingCompares 2U, posted on Facebook that she had overdosed in a hotel room, prompting thousands of fans to worry, with some even calling police.

The mother of four posted an anguished message about being abandoned, the victim of cruelty at the hands of her family and no one caring whether she lived or died.

O’Connor, who suffers with mental illness, has been open about her struggles with manic depression in the past, telling Sky’s Entertainment Week: “When you admit that you are anything that could be mistakenly, or otherwise, perceived as ‘mentally ill’ you know that you are going to get treated like dirt so you don’t go tell anybody and that’s why people die.”

The singer was found safe in an unidentified hotel.

There is only so much any woman can be expected to bear. What was done to me this week was appalling cruelty. By my husband, my family, by St Pats and by An Gardai Siochana, by my son, Jake and by Donal Lunny and Angela singleton, by my son’s girlfriend, his friends… after everything I’ve been put through and been forced to go through alone .. And punished for having to go through since I had the surgery on August 26th. Or since Shane became unwell in March, This week has broken me. The withholding of my babies from me without any sound reason by their fathers, Frank and Donal, and by Jake and the rest of my family, is a horrific set of betrayals. And has been going on since I had my surgery. The last two nights finished me off. I have taken an overdose. There is no other way to get respect. I am not at home, I’m at a hotel, somewhere in ireland, under another name

If I wasn’t posting this, my kids and family wouldn’t even find out. Was dead for another fortnight since none of them bother their hole with me for a minute. I could have been dead here for weeks already and they’d never have known. Because apparently I’m scum and deserve to be abandoned and treated like shit just when I’ve had my womb and ovaries chopped out and my child is frighteningly sick. I’m such a rotten horrible mother and Person, that I’ve been alone. Howling crying for weeks. And been told by them all t go fuck myself. I’m invisible. I don’t matter a shred to anyone. No one has come near me. I’ve died a million times already with the pain of it. So yeah.. Strangers like me.. But my family don’t value me at all. They wouldn’t know if I was dead until weeks from now if I wasn’t fucking informing them now.

well done guys, you’ve finally got rid of me. Sorry the penny didn’t drop sooner. I’m an idiot. When you planned to get me away from my babies did you plan for me losing my mind over it? It being the final straw? For how you’re gonna explain why I died? Make sure you tell the truth. BARRY.. THEY WONT. YOURE THE ONLY ONE WHO KNOWS ME OR THE TRUTH. PLEASE STAND FOR ME AND TELL IT. i can’t play twister. My children don’t care if I live r die anyway. Neither do their dads. Everyone is better off. Never ever do this to a woman again. Let this be your lesson. I survived it when John waters did it.. I can’t survive Jake doing it.
